TYIRE CONSTRUCTION.

Application led April 18, 1922. Serial No. 555,287.

To all whom t may concern: 4 Be it known that l, ALFRED ANCiDoNL a citizen of the United States, and residing at Newark, in the lcounty of Essex and State of New Jersey, have invented certain new and useful improvements in Tire Constructions, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to tires and particularly to devices of this class adapted for use in connection with motor vehicles, and the object of the invention is to provide a resilient tire composed of a plurality of resilient units mounted in juxtaposition in a circumferential path to form an annular resilient tire member, the separate units being independent of each other and being adapted lto be detachably mounted in connection with a suitable support; a further object being to provide a support for said resilient units which will constitute a demountable rim for the wheel of a vehicle and in connection with which said units are mounted and capable of independent attachment and detachment therewith; and'with these and other objects in view the invention consists in a tire of the class and for the purpose specified which is simple in construction and operation, strong and durable in use and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable referencev characters in each of the views, and in which Fig. 1 is aside view of a part of the felly of a wheel showing a predetermined portion of my improved tire construction, part of the constructionbeing broken away and in section- Fig. 2 a sectionpon the line 2-2 of Fig. 1 and, 1

jF ig. 3 a partial sectional view similar to Fig. 2 andshowing a modification.l

In the drawing, I have indicated at 10 a felly of a motor vehicle wheel, said felly being provided with 'a metal facing plate or ring 11 having a {iange 12 at one side thereof preferably the inneriside and, in practice, my improvedtire construction 13 is adapted to be detachably mounted in connection with said felly and held in position thereon in the usual manner or any desired manner.

My improved tire construction comprises a plurality of resilient units 14; adapted to 60 be mounted in connection with a demount-` able rim 15 which is approximately U-shaped in form in cross section as shown in Fig. 2 of the drawing. Y

The resilient units 14e-are each composed of a base plate or disk 16 and a member 17 spaced from the disk 16 by semi-spherical resilient members 18 and 19, the member 18 being mounted in the disk 16, while the member 19 is mounted on the inner face of the member 17. Mounted in the outer face of the member 17 is a resilient tread mem- ,l ber 2() which is also approximately hemispherical in form, and the members 19 and 2() are separated by a transverse wall 21 in the member 17 and a bolt, rivet or the like 22 is passed through the wall 21, the resilient members 18 and 19 and through said disk, as clearly shown in Fig. 2, and a cupshaped member 23 is mounted in an aperture 24: in the rim 15 and the flange 25 thereof serves to space said rim from the plate 11 of the felly 10, as clearly shown in said figure, and the nut 26 of the bolt 22 or the head of the rivet, if said device be a rivet, is located within the recess 27 of the `cup-shaped member 23.

lt will be apparent that the bolt or rivet 22 serves to hold the separate parts 16, 17, 18, 19and 23 together and in position upon the demountable rim 15, as clearly shown in F ig.V 2, and the resilient tread member 20 is preferably provided with a central pocket or chamber 28 to permit of the passage of the head of the bolt or rivet 22 outwardly 9 through said pocket or chamber in the operation of the tire or the separate units 14 thereof. It will be understood that as the separate units 14 pass over the ground or road-way the resilient members 18 and 19 will be compressed to a predetermined degrec and the member 17 will move inwardly upon the bolt or rivet 22 in this operation.

t will be understood that each of the units 14C employed will be constructedin the 105 manner above set out, and these units when assembled and mounted upon the rim 15 will constitute a part of such rim and may be mounted in connection with a wheel, or the telly thereof, by simply passing the same n@ inwardly over the plate 11 of said felly and will be held against displacement by the flange 12 of saidplate and by the usual lock plates or devices commonly employed in retaining demountable rims in connection with Wheels.

As shown in the drawingthe. members 17 oi' the separate units 1A are circular in orm` andare so assembled as to come in comparatively close relation one with another Yto form a substantially annular tire member composed of the separate units, but it will be understood that I am not necessarily limited i'tothe' specific mounting ot' the units, as herein shown and described, nor to the specificzconstruction thereof herein set out.

Tn,'yFig. `3` 'ofthedraiving l have shown a. slight modification otthe 'separate units in which the member 17 is provided ivith an inwardlyl directed sleeve extension 17, and thefdislr 16' is provided with an outwardly directed "sleeve extension 16 adapted to fit Within the' 'sleeveextension 17, and these sleeve'iextensions serve to form an enclosure foritheresilient members 1S and 19, and Whilel l haye'shown certain details of construction forK carrying my inventionA into effect", it'will be'i'ujiderstood` that l am not necessarilylimitedfto thes'edetails, andl various changes" therein and modifications there'ot may be made, Within the scope` ot thelappended claims, without departing from the'spir'it of my invention` or sacriicing; 'its advantages.
